    Abstract: 一种双PWM变流器直流母线电压波动抑制方法及控制方法。其中,直流母线电压波动抑制方法包括以下步骤:建立网侧、负载侧及中间电容(200)之间的功率平衡方程;建立中间电容的电容瞬时有功功率小信号模型;建立负载侧的负载瞬时有功功率小信号模型;根据电容瞬时有功功率小信号模型、负载瞬时有功功率小信号模型及功率平衡方程计算网侧瞬时有功功率参考值(p*);将网侧瞬时有功功率参考值作为功率参考对网侧变流器(100)进行反馈控制。功率参考中包含了直流母线电压纹波及负载(400)状态变化信息,其有效性更高;同时,网侧变流器的调节兼顾了负载变化对母线电压的影响,从而减小了直流母线电压的波动。

    Abstract: A bidirectional low voltage power supply (LVPS) for providing power to motor drive electronics. The bidirectional LVPS includes two simple, discrete converters. A first converter is used to provide power to an output and the second converter recycles power from the output to the power source. The first converter powers the drive electronics which drives the motor. During an operating process, the first converter shuts off and the second converter turns on to recycle power from the motor to the power source.

    Abstract: Apparatus for energizing a large scale medical imaging system, preferably in the form of a CT scanner, so that the scanner operates off an uninterruptable power supply (40) in the event that the external power (46) falls below sufficient power to operate the system so that system operation remains uninterruptable. The system is designed to operate off a broad range and types of external power supplies (46) including those providing DC, single or three phase AC power. The system therefore can operate from a common single phase AC outlet. In addition, power factor correction (80) is provided so that the system can correct for phase differences between the voltage and current at the input line (46) created by the input impedance of the system.
